Onion (Allium cepa) and garlic (Allium sativum), belonging to the same genus ‘Allium’ has a lot of similarities in their chemical composition, but differ in their reactions.

Growing up in the USA, ten-year-old Steven was asked in school to read aloud a passage from a newspaper. The article described the opening of the first Disneyland. However, all the poor boy could see on the paper was this—“In a grand ceremony Disneyland opened in California to delirious applause.” Steven Spielberg did not know it at the time—and indeed until he was formally diagnosed several years later—that he was dyslexic.
If you were a travelling salesman, who travels to many places selling something, the most challenging part of the job is to find the shortest route to these places without visiting any of them twice.

In 1908, a meteoroid (a small asteroid) exploded in the atmosphere near the Stony Tunguska River in Eastern Siberia, flattening over 2000 square kilometres of forest. Luckily, the region was very thinly populated, and there were no casualties. But, our Earth is not always that fortunate! Billions of years ago, our planet is thought to have been struck by many such asteroids, creating a dent on its surface.
Imagine streaming a movie through your tube light or accessing the Internet through a street lamp. Light Fidelity (Li-Fi), a new communication system developed by Professor Harald Hass, can actually achieve this!
Our genes affect every aspect of our lives, from the way we look to the diseases we get. However, they don't act in an isolated manner, because we are also affected by the environment we live in. Our diet, exercise levels, pollution levels in the place we live – all affect what happens to our bodies.
How do scientists proclaim an ecosystem like the Western Ghats as an ‘biodiversity hotspot’ and push for its conservation? They do so by ‘ecological sampling’, a technique used to find diversity and abundance of animals and plants in a habitat. They collect samples of plants and animals from different locations within an area and extrapolate the possible biodiversity that exists in the area.
If someone came up to you and said the stool from one person can be used as medicine to treat another, you’d most likely be disgusted or find it absurd. It sounds incredible, but it is true.
Mosquito bite! That’s all you need to express your killer instinct. But this allegedly innocent, tiny little arthropod with jointed legs, dressed in black and white stripes like an escaped prisoner, bites just for its ‘daily blood’.
